Figure S1. (a) Results from simulations of random mating compared to observed values (filled circles) of the mean inbreeding coefficient (F) in the adult population. (b) Overview of our ability to detect inbreeding avoidance by the first mate choice rule (random mate choice among males with which the female in question shares a kinship coefficient lower than the threshold value, kthresh).

Figure S2. Overview of our ability to detect inbreeding avoidance by the second mate choice rule (random mate choice from among the proportion, rprop, of males that are the least related to the female, measured by the kinship coefficient).

Figure S3. Overview of our ability to detect inbreeding avoidance by the third mate choice rule (random mate choice among males with an inbreeding coefficient lower than a threshold value, Fthresh).
